To all whom, 2'25 may concern: Be it known that I, WILLIAM T. citizen of the United States, residing at St. Louis, State of Missouri, have invented new and useful Improvements'inRail-Joints, of

ORii, a

which the following is a speoication.

y/'adapted vto seat. The upper dove-tailed l This invention relates to rail joints and the object of the invention is the provision of a combined rail chair and tread joint which is adapted to connect theends of separate `rails together without the use of bolts or other fastening devices and which will permit ready expansion or contraction of Athe rails.

A further object of the invention is the provision of means for efl'ectually preventing lateral disengagement of the sh plate' sections of the joint without the use of bolts.

' Further objects ofthe inventionwill appear asF the following specific description is lread in connection with the accompanying.

drawing which forms apart of this application, and in whichl Figure 1 is'a side elevation. Fig. 2 is a top plan View. Fig. 3 is a section on the line 3 3 of Fig. 2.

Referring more particularly to the drawl ing 1 and 2 represent the ends of the sepa; rate rails which are to be connected and 3 represent-s theO combined chair and tread joint. This combined chair andtread joint is made of van integral casting having a base 4, which extends beneath `the base of the rails and is formed with the inwardly extending ianges 5, having a groove 6 which is adapted to receive the base of the rail 7. Extending upwardly from the flanges 5 are` the vertical fish plate sections or flanges 8 and 9 the former extendingup flush with the tread of the rail and formlng a seat l0 for the wheel which rides thereover without being affected bythe space between the rails. as shown at 11 and the base 7 `is also undercut as at 12 so as to forma dove-tailed groove or mortise 13 in which the dove A tailed edges 14 of the flanges 8 and 9 are It will be noted-from The heads of the rails are undercut edge on the flange 9 is formedbycutting away the tread 1 0 inthe-manner shown. Suitable spike apertures 15 are provided to prevent the device from slipping longitudinally on the rails; the dovetailed connection of the anges 8 and 9 with the rail absolutelyprevents any It will be noticed that` lateral movement 'of these. flangesv and avoids the use of'bolts as in the attachment of the ordinary fish plates;

In 'applying the device the ends' of vthe',

rails are slipped in ,toward'each other until they abut and the device is then spiked to.-

the adjoining ties.

drawing that onejof the outer side faces *ofv the chan' memberI inclines outwardly roni the opposite free ends thereof 4and terminateslinterniediate the said 'ends in' anfen-l larged, thickened portion the transverse cen-v in alinement with the meetingends ofthe rails, forming a substantial reinforcement for rail ends at their .meeting portionszjj .ter of the thickened portion. being arranged l Having thus described the :invtnti'on, what` is claimed is'- A-rail chair comprising a base-'adapted support the meeting "ends, ofthe railsand'a base flange extending inwardly therefromi the heads of said rails han/ingA their underside beveled upwardly and inwardly 'toward their webs, the bases of said rails-having their upper surfaces inclined from the'` nenter thereof in opposite directions, V"splice Jars rising upwardly from said flanges and having their upper edges oppositely'gbeveled to engage the beveled portion of said l1eads, l

and said. base flange having its underface oppositely inclined afrom the center-,to cor-n respond to and engage the oppositely 1n'-` clined portion of the base 1n a manner-and;

In testimony whereof I arlx my signature for thepurpose described. 1
